It has a 202 amino acid extracellular domain and a short (19 aa) cytoplasmic tail. At least two alternate splice isoforms exist that differ in their cytoplasmic domains. CD200 is widely expressed in multiple cell types. It interacts with CD200 R1, another Ig superfamily inhibitory receptor primarily expressed on leukocytes of the myeloid lineage, to inhibit myeloid functions.
